READ CAREFULLY BEFORE ATTEMPTING ALIGNMENT
1. Set volume control to maximum.
5. Set power source voltage to 9V DC.
2. Set tone control to center.
6. Set FM MODE/B.P switch to STEREO.
3. Set band switch to FM,LW,MW,or SW.
|
7. Output of signal generator should be no higher than necessary
4. Set function selector to RADIO or TAPE/OFF.
